Layout Considerations

PCB Layout is important to achieve stable operation for switching power system at the high switching frequencies

and high peak currents conditions. For best results, follow these guidelines:

(1) The input capacitor placed as close and wide as possible to V

(2) The output capacitor placed as close and wide as possible to V

(3) Place Lx Pin as short and wide to the IC as possible.
